RS-232 and other serial ports and interfaces pinouts listing

• EIA/TIA-562 serial interface TIA/EIA-562 is a very similar to TIA/EIA-232-F with data rates up to 64 kbps supported.
• EIA/TIA-694 serial interface This is an electrical standard, similar to RS-232-F, but with data rates up to 512 kbps support.
• ITU-TSS V.35 interface Basically, V.35 is a high-speed serial interface designed to support both higher data rates and connectivity between DTEs or DCEs over digital lines.
• ITU-TSS X.21 interface Common names: ITU-TSS (CCITT) X.21, ISO 4903
• PC serial (25 pin) Very common PC serial port.
• PC serial port (RS-232 DE9) This RS232C DE-9 (usually miscalled DB-9) port is very common and available at almost any PC, some Sun (at least Ultra 5/ 10, Blade 100/150) and many other computers. Document includes description of how PC serial mouse works.
• RS-232 (EIA-232) serial interface RS-232 is the standard serial communications interface found on all types of equipment such as computers, modems, printers, Microcontrollers, eprom programmers, and a host of other devices. Identical to the CCITT V.24/V.28, X.20bis/X.21bis and ISO IS2110 standards. RS232 pinout may be varied.
• RS-232D 
• RS-366 interface 
• RS-422 (9 pin) 
• RS-422 (EIA-422) serial interface RS422 is a balanced serial interface for the transmission of digital data. The advantage of a balanced signal is the greater immunity to noise. The EIA describes RS422 as a DTE to DCE interface for point-to-point connections.
• RS-423 (TIA/EIA-423-B) serial interface It is similar to TIA/EIA-232-F, but features a reduced driver output swing and higher data rates.
• RS-449 (EIA-449) interface The RS449 interface is a generic connector specification. It´s not an actual interface. The connector pinning was originally designed to support RS422 for balanced signals, and RS423 for the unbalanced signals. And should have been the succesor of RS232.
• RS-449 (EIA-449) Secondary Common names: EIA-449, RS-449, ISO 4902. Secondary (auxilary) channel
• RS-485 (EIA-485) serial interface has no common pinout
• RS-530 (EIA530) interface EIA-530, or RS-530, is a balanced serial interface standard that generally uses a 25 pin connector. The RS530 isn't an actual interfaceis, but a generic connector specification. The connector pinning can be used to support RS422, RS423, V.36/V.37/V.10/V.11 (not V.35!) and X.21 to name the most popular ones.
• Serial (Printer) 

• Apple GeoPort The back panel of all Power Macintosh models contain two I/O ports for serial telecommunication data.
• Apple IIc Serial Port This is the Apple implementation of the RS-232c interface for the Apple IIc (not IIc+) computer
• Apple Macintosh RS-422 It´s possible to connect RS-232 peripheral to the RS-422 port available on Macintosh computers. Use RXD- as RXD, TXD- as TXD, Ground RXD+, Leave TXD+ unconnected, GPi as CD.
• Apple Macintosh Serial This connector is present on Macintosh 128K, 512K, and 512K enhanced.
• Apple Macintosh XL Serial A 
• Apple Macintosh XL Serial B 
• AppleLine RS232 

• Cisco Auxiliary port for Cisco 1000, 1600, 2500, 2600, and 3600 series routers The auxiliary port is configured as data terminal equipment (DTE)
• Cisco Console port (at Catalyst 5000 Series Switch) The Cisco Consule port is used on the Cisco Catalyst 5000 Series Switch Supervisor Engine III
• Cisco console port for Cisco 1000, 1600, 2500, 2600, And 3600 series routers The console and auxiliary ports on Cisco IOS routers are asynchronous serial ports. The console port is configured as data communications equipment (DCE)
• Cisco console port for Cisco 700 series routers 

• DEC DLV11-J Serial Available on the DEC DLV11-J Serial card
• DEC Dual RS-232 Found on the DEC Multia and DEC UDB (Universal Desktop Box). It contains two Serial ports on one connector. The 1st port is located on the normal pins, and the 2nd port is located on some "spare" pins.
• DEC MMJ MMJ=Modified Modular Jack. Invented by Digital Equipment Corporation (DEC) (now: Compaq)

• ATARI Serial Input/Output (SIO) 
• C64 RS232 User port Available on the Commodore C64/C128. Software emulated. The signals does not have true RS232 levels. It´s TTL level, and RXD/TXD is inverted. It´s just the normal User port, used as a RS232 port.
• C64 Serial I/O Available on the Commodore C64, C16, C116 and +4 computers
• CoCo Serial Printer Available on the Tandy Color Computer, also known as CoCo.
• MC-10 Serial port 
• Serial (Amiga 1000) 
• Serial (Amiga) 
• Serial (MSX) 

• Serial (SGI MiniDIN) Mini-DIN-8 serial port connectors are found on the Personal IRIS 4D/30, 4D/35, Indigo, Indy, and Indigo2. Most of other SGI workstation uses standard PC serial pinout.
• SGI serial port This connector can be found on Challenge, Onyx, Personal IRIS, and Power Series systems

• SUN Sparcstation 4, 5, 10, 20, LX, Classic, Classic X, Ultra Enterprise 450 Serial port This port is located in SUN Sparcs such as SUN LX/Classic/SS4/5/10/20 and has both serial ports (A/B) in the same connector. Simply plugging in a regular serial cable in results in accessing port A.
• Sun Serial (DB25) Available on SUN computers since the SUN3 series (1988) to the current UltraSparc systems (RS423/RS232)
